Mental Health: A Key Reason for Sickness Absence

A new YouGov survey commissioned by Acas shows that almost one in three employers are finding that stress, anxiety, depression or other mental health problems are a reason that staff give for sickness absence.

The top reason for sickness is minor illnesses, such as coughs, colds and the flu.

The Employment Rights Act 2025 brings new rules into effect from 6 April 2026 that will make workers eligible for statutory sick pay for their first day of illness rather than the fourth day. Workers also no longer need to earn more than a minimum amount to be eligible.

Acas have provided four suggestions that can help employers manage, and perhaps reduce, sickness absence.

• Provide training to managers on how to support employees through a period of illness.
• Offer flexible working that helps to promote a healthy work environment.
• Have processes in place to help resolve workplace issues that can spark sickness absences.
• Have accessible and clear illness and absence policies so that everyone knows what is expected should someone need time off work.

Acas has updated its guidance on sick pay in light of the new rules.
